Caveats
- Properties named with funky names (like "!breaks", "|breaks", etc) or keyword (like "this", "break", "class", etc) will produce syntax errors.
- Equal structures are not detected yet (Equal classes are going to be created over and over).
- When an empty array is given, it will create a List. Such weird behaviour should warn the user that there is no data to extract.
- Array of arrays are not supported:
[[{ "isThisSupported": false }]]
[{ "thisSupported": [{ "cool": true }] }]
